Title: Transparent heating elements and a process for producing the same
IPC: H05B3/14
Filed: 1968-05-31
Abstract: 1,220,748. Heating resistors. KLIMATECHNIK ANSTALT. 31 May, 1968 [2 June, 1967], No. 26192/68. Heading H5H. A transparent heating element is made by swelling a transparent plastics film in a transparent electrolyte dissolved in a suitable solvent, forming terminal connectors on the film and hermetically sealing the electrolytic heating film so formed in a plastics envelope. Terminal connectors on the envelope engage those on the conducting heating film, both being in the form of silver strips. Although electrolytes have a negative temperature coefficient, the heating element has a positive temperature coefficient because the solvent evaporates into the envelope on rise in temperature. If a hygroscopic material is incorporated in the electrolyte the solvent is re-absorbed on cooling.

Patent GB-267510-A (GB)
Abstract: 267,510. Wanderer Werke vorm. Winklhofer & Jaenicke Akt.-Ges. March 11, 1926, [Convention date]. Adding-apparatus. - An actuating mechanism for a typewriter calculating-machine is of the pinion and stepped barrel type and is so arranged that on depression of a key the power drive becomes effective to slide the pinion along the barrel to the required position and at the same time to commence rotating the barrel. A; bar 4 tending to slide to the right under the action of a spring 10 is normally restrained by a projection 12 of the bar engaging a pin 13 on a disc 14 mounted loosely on but connected by a spiral spring 18 with a hub 16. When a numeral key is depressed the one-cycle drive of the shaft 1 is instituted by suitable means and this drive is conveyed through bevel gears 20 to a spur-wheel 16 fixed to the hub 15. The wheel 14 thus commences to revolve and the bar 4 being released by the pin 13 moves to the right until its end strikes the key stop 11 to position the pinion 7 according to the key used. Later in the cycle an arm 22 normally in the path of a lug 23 on wheel 14 detains the wheel 14 so that the spring 18 is wound up to effect, upon subsequent release of the lug, by cam control of arm 22 from shaft 1, the return of the bar 4 by the pin 13 and the restoration of the mechanism to normal condition.

Title: Process for pre-treatment of polymers and modified polymers obtained thereby
IPC: C08J3/11
Filed: 1954-09-15
Abstract: Particulate thermoplastic polymers of ethylenically unsaturated monomers are rendered readily dispersible and non-swelling in the cold in solvents by heating the polymer at such a temperature and for such a time that a layer of degraded polymer is produced at the surface only of the particles.  The heating may be effected by suspending the particulate polymer in a non-solvent liquid such as water or ethylene glycol, and heating the liquid or blowing a current of steam through it, or by suspending the particles in a stream of hot gas, e.g. nitrogen, at 120 DEG  C.  Specified polymers are polyvinyl chloride, polyacrylonitrile, and copolymers of acrylonitrile with vinylpyridine or ethyl acrylate.  Solutions formed by heating dispersions of the polymers in organic solvents are used in the manufacture of fibres and films.  Specifications 712,568 and 735,183 are referred to.

Title: Tabulating card reader
IPC: G06K7/04
Filed: 1960-08-02
Abstract: 922,236. Sensing record cards. COMMERCIAL CONTROLS CORPORATION. Aug. 2, 1960 [Oct. 12, 1959], No. 26771/60. Class 106 (1). A record card senser comprises feed rollers, means for driving the rollers in angular steps corresponding to the spacing between columns on the card, means for sensing the perforations in the card and manually actuable means for separating and closing the feed rollers and for concurrently projecting and withdrawing one or more leading edge stop members to preposition a card in readiness for sensing. The rollers 23, 44, Fig. 3, are separated for manual insertion of a card and the front-edge stop 33, Fig. 5, is raised by lifting the control lever 29 to the position shown dotted in Fig. 3. The top rollers 23 are idlers and are carried on arms 26 connected by a cross-piece 39. Spring 42 normally holds the rollers 23 pressed against the driving rollers 44 but rotation of lever 29 causes a pair of lifting rollers 51 to bear against the cross-piece and raise the rollers 23. The springs 33 acting as a front stop are attached to the cross-piece 39 and rise into the path of an inserted card. Spring arms 53 bear downwardly on the stops in their operative position to prevent the card passing over the stops. The card is inserted over a table 13 having side guides 16, 17, Fig. 1, and a lipped front end guide 18. When the card is in position a card-lever 21 is depressed which closes a switch so that sensing can take place. The lever 29 is lowered to clamp the card between rollers 23 and 44 and to lower the front end stops 33. Shaft 101 is driven to step the card through the machine, a cam causing oscillation of a pawl which engages teeth on a gear-wheel on shaft 45 to feed the card one column's space between sensing operations. A row of sensing pins 54 vertically slidable in block 56 are normally held down by a bail 106 bearing on levers 107, one for each pin. The levers are spring-loaded in an upward direction so that when the bail 106 is lifted the pins rise to sense the card. Abutments 109 on the levers 107 control the positions of levers 84, each of which controls a combination of contacts 77 through a spring blade 81 and link 83. Where a hole is sensed the corresponding pin and lever 107 rise so that the associated lever 84 can rotate and transfer the contacts. After a sensing operation the lever 102 is rotated anticlockwise to reset the sensing pins, a spreader being forced between rollers 89 on arms 86 so that bails 87 return levers 84 to the home position. The bail 106 bears downwardly on the levers 107 to return the pins to the inoperative position. Parity check.-The contacts associated with each sensing pin are connected in a network circuit to provide a binary scale output on parallel leads. Diodes are used in the network to prevent back connections. The circuit is arranged so that wherever an even number of output leads would be energized, a further lead is energized to keep the number of energized leads odd. Specifications 831,111,832,908 and 922,235 are referred to.
